CLEAN ROOM SOFTWARE ENGINEERING CSC-532 By Srinivasa Yanaparti

Introduction: It Goes against the traditional approach of software engineering. To avoid dependence on cost defect removal process Its process model incorporates the statistical quality verification of code increments as they accumulate into a system.

Clean room process Flow:

Clean room Management Processes: Project Planning Process Project Management Process Performance Improvement Process

Clean Room Specification Processes: Requirement Analysis Process Functional Specification Process Usage Specification Process Architecture Specification Process Incremental Planning Process

Clean Room development Processes: Software Reengineering Process Increment Design Process Correctness Verification Process

Clean Room Certification Processes: Usage Modeling and Test Planning Process Statistical Testing and Certification process

Advantages of CSE: Improve the quality Increase productivity Improve software maintainability

Disadvantages of CSE: Too theoretical ,too mathematical and plain too radical for software development. Denying the programmer access to the compiler is unrealistic and can be counterproductive.

Conclusion: The CSE methodology uses controlled and measurable statistics to eliminate or avoid as many defects as possible before software execution. It supports prototyping , object orientation and reuse. It can be applied to new system as well as existing systems.
